System Administration :\n\n- Deploy, configure, and maintain Linux servers across distributions including Ubuntu, Red Hat, and CentOS in production and staging environments.\n\n- Perform advanced system performance tuning: CPU pinning, NUMA topology optimization, IRQ affinity, huge pages configuration, and kernel parameter tuning (sysctl).\n\n- Manage OS-level scheduling policies, real-time priorities (SCHED FIFO/SCHED RR), and CPU isolation (isolcpus) to eliminate jitter.\n\nHFT Infrastructure & Low-Latency Engineering :\n\n- Manage and optimize bare-metal HFT trading infrastructure with a relentless focus on determinism, performance, and latency reduction.\n\n- Support HFT architecture and workflows including market data ingestion, order management systems (OMS), and execution infrastructure.\n\n- Manage exchange connectivity, colocation environments, and co-location service provider relationships.\n\n- Work with ultra-low latency network hardware: 10/25/40/100GbE NICs, including Solarflare and Mellanox/NVIDIA ConnectX adapters, and Cisco Nexus X25 SmartNICs (K3P-S).\n\nData Centre & Network Operations :\n\n- Administer data centre Linux environments including rack management, cabling, power, and cooling coordination.\n\n- Manage L2/L3 data centre networks including VLANs, spanning tree, BGP/OSPF routing, and multicast (PIM-SM) configurations.\n\n- Configure and manage high-speed network switches (Cisco Nexus series) for ultra-low latency operation.\n\n- Support market data distribution infrastructure and feed handlers connected to major exchanges.\n\n- Ensure network high availability through redundant paths, failover configurations, and proactive capacity planning.\n\nStorage, Monitoring & Automation :\n\n- Manage high-performance storage systems including NVMe SSDs, RAID configurations, and high-throughput storage arrays used for tick data and trading logs.\n\n- Build and maintain monitoring and alerting infrastructure using Prometheus, Grafana, and custom latency dashboards to provide real-time visibility across all systems.\n\n- Automate routine infrastructure tasks using Bash and Python scripting, including deployment automation, health checks, log rotation, and configuration management..\n\nQUALIFICATIONS :\n\n- Bachelor's degree (BE/B.Tech) in Information Technology, Computer Science, Electronics, or a closely related engineering discipline.\n\n- Linux certifications strongly preferred: RHCE (Red Hat Certified Engineer), RHCSA (Red Hat Certified System Administrator), or LPIC-1/LPIC-2 (Linux Professional Institute Certification).\n\n- Networking certifications preferred: CCNA (Cisco Certified Network Associate) or CCNP (Cisco Certified Network Professional).\n\n- 3 to 8 years of hands-on experience administering Linux systems in production, with at least 2 years in HFT, financial services, or low-latency computing environments.\nSkills\nSystem Administration, Linux, IP Networking, Security,
